Java automatically creates multi-level catalogs

//Create file Upload path     Public Static voidmkdir (String path) {File fd=NULL; Try{FD=NewFile (path); if(!fd.exists ())            {Fd.mkdirs (); }        } Catch(Exception e) {e.printstacktrace (); } finally{FD=NULL; }    }

Often meet when you create a directory
Throws an exception because its previous level directory, the parent directory, does not exist (the specified file path does not exist)
The JDK provides two ways to create a directory to implement MkDir () and Mkdirs ()
The former creates the specified directory under the path parameter of the given directory structure.
Throws an exception if a directory is missing from the path (FileNotFoundException)
The second method, however, is a relatively safe implementation because he automatically creates a nonexistent parent directory.
